What is redux-saga?
Who uses redux-saga?
Why developers like redux-saga?
Here are some stack decisions, common use cases and reviews by companies and developers who chose redux-saga in their tech stack.
Choosing redux-saga for my async Redux.js middleware, for a React application, instead of the typical redux-thunk .
Redux-saga is much easier to test than Redux-thunk - it requires no module mocking at all. Converting from redux-thunk to redux-saga is easy enough, as you are only refactoring the action creators - not your redux store or your react components. I've linked a github repo that shows the same solution with both, including Jest tests.
Working on a project recently, wanted an easy modern frontend to work with, decoupled from our backend. To get things going quickly, decided to go with React, Redux.js, redux-saga, Bootstrap.
On the backend side, Go is a personal favourite, and wanted to minimize server overheads so went with a #serverless architecture leveraging AWS Lambda, AWS CloudFormation, Amazon DynamoDB, etc.
For IDE/tooling I tend to stick to the #JetBrains tools: WebStorm / Goland.
Obviously using Git, with GitLab private repo's for managing code/issues/etc.
After splitting our monolith into a Rails API + a React Redux.js frontend app, it became a necessity to monitor frontend errors. Our frontend application is not your typical website, and features a lot of interesting SPA mechanics that need to be followed closely (many async flows, redux-saga , etc.) in addition to regular browser incompatibility issues. Rollbar kicks in so that we can monitor every bug that happens on our frontend, and aggregate this with almost 0 work. The number of occurrences and affected browsers on each occurence helps us understand the priority and severity of bugs even when our users don't tell us about them, so we can decide whether we need to fix this bug that was encountered by 1k users in less than a few days days VERSUS telling this SINGLE user to switch browsers because he's using a very outdated version that no one else uses. Now we also use Rollbar with Rails, Sidekiq and even AWS Lambda errors since the interface is quite convenient.
Back at early 2017 the confusion and controversy around the future of AngularJS was at full swing. Also, the Angular 2 looked quite restrictive (or prescriptive even) when we did the assessment what to choose for Katana. React came out on top because it's community looked healthier, future more solid. And as you all know, one decision leads to many others: Redux, redux-saga , Axios
For async requests in React I use redux-saga , to my opinion it is the most organized framework for async requests, it is clearer then redux-thunk and conforms to the style of Redux.js which results in a more structured project, especially in large web applications. #redux-saga
